Title: Improvements in or relating to the concentration and reduction of iron ore
IPC: C22B1/14
Filed: 1947-06-17
Abstract: A process of concentrating ore comprises the steps of effecting a dry, thermal partial reduction of the iron in the ore to the metallic state to a degree of reduction between 50 and 80 per cent, subjecting the product to magnetic separation and recovering the magnetic concentrate.  The partial reduction may be carried out at temperatures not exceeding 1000 DEG C by means of solid carbonaceous reducing agents such as coal or coke.  The mixture of ore and reducing agent may be caused to travel along a rotary chamber of substantial length in relation to its cross-section, air being admitted at several points along the length of the vessel, the amount of air or oxygen being adjusted so that the carbon monoxide formed by the reduction is substantially burnt to carbon dioxide in the chamber. Specification 636,677 also is referred to.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 662,521, and also refers to the use of a stationary furnace.  This subject-matter does not appear in the Specification as accepted.

Filed: 1972-04-07
Abstract: 1359087 Vibrators W A ATHAWES 7 April 1972 16279/72 Heading F2X A rotary vibrator comprises a housing 11 closed at its ends by a pair of end plates 25, 26 having axial bores 29, 30 through which bolts 31, 32 are inserted, an axial pin 33 between plates 25, 26 being formed with axial threaded bores 36 for receiving the threaded ends of the bolts 31, 32 and so securing the end plates 25, 26 to the housing 11. The pin 33 has a peripheral bearing surface 42 in the form of a continuous circumferentially extending V-shaped recess and is located within an annular rotor 38, the bore of which has a cross-section conforming to that of the pin bearing surface 42. Fluid, e.g. air, under pressure is fed into the housing 11  via an inlet passage 19, a similar passage 18 functioning as the exhaust outlet, to cause the rotor 38 to revolve about the pin 33 with a portion of the V-shaped projection of the rotor always received within a portion of the V- shaped recess of the pin, whereby movement of the rotor in a direction parallel to the axis of the pin is substantially prevented. Thus contact between the end faces of the rotor and the inner faces 28 of the end plates 25, 26 is minimized. The pin and the rotor are preferably formed of hardened ground steel or, alternatively, their bearing surfaces may be formed of hard facing alloy. In operation, the device is attached by bolting through holes 14a to the object to be vibrated, e.g. core boxes, match plates, &c., used in metal casting or hoppers, delivery shoots, &c. to ensure the flow of powdered materials. The fluid inlet may include a plurality of orifices spaced apart along the housing wall in a direction parallel to the pin axis (Fig. 4, not shown). In alternative constructions, the V-shaped recess is provided in the rotor and the V-shaped projection on the pin (Fig. 5, not shown), the rotor is located on the pin by a ring of rectangular cross-section turned on the pin outer wall and accommodated within a conforming recess in the rotor bore (Fig. 6, not shown), and the pin is provided with two spaced apart rings or ball-bearing assemblies which engage in spaced apart recesses in the rotor bore (Figs. 7 and 8, not shown).

Abstract: 1,106,115. Delivering measured quantities of granular material. B. E. RASMUSSON, and L. W. BUSCH. 26 Jan., 1966 [28 Jan., 1965], No. 16454/67. Divided out of 1,106,114. Heading B8N. An apparatus for delivering measured quantities of granular material such as coatings to confections as described in Specification 1,106,114 comprises a tubular member 50 having openings 56, 58 and rotatable to a position in which the openings are aligned with a supply hopper 40 and a discharge opening 64 respectively and means for delivering a momentary blast of air axially into an end of the member while it is out of the above position to cause material in that end to move to the opposite end. The tubular member 50 is rotated by means of a piston-operated rack 72 engaging with a pinion 70 on the member. The air is fed through the member via a coupling 76 and passes out of the member via a mesh strainer 84 located in a removable sleeve 82. In operation, with the member in the position shown, material in the hopper 40 falls into the opening 56. Upon actuation of a first valve 160, Fig. 10, the piston-operated rack 72 is moved so as to rotate the tubular member into a position in which the outlet from the hopper and the discharge opening are closed. A second valve (162, Fig. 10) is then actuated so as to cause a blast of air to move the material along the tubular member until stopped by the mesh 84, the air escaping through the latter. When the valve 160 is again actuated the tubular member is rotated to its initial position so that the material falls out of the opening 58; a deflector plate 66 is provided.

Locks, revolving- barrel; with special means for operating bolts.-A lock for securing motor vehicles and their accessories &c. has balls or rollers which are protruded from, or withdrawn within, the casing by the longitudinal movement of a member actuated by a revolving barrel. Fig. 1 shows the balls 17 in the locking position. To unlock, the pins 7 are pressed in by a suitable key, allowing the barrel 5 to be rotated. Its square shaft 5<b> rotates the sleeve 8, the external thread of which engages the internal thread of the member 12, imparting a longitudinal movement to it.
